2006 MERCEDES-BENZ SL65AMG coolant

448 Technical dataFuels, coolants, lubricants, etc.Premium unleaded gasoline
Fuel requirements
Only use premium unleaded fuel:

The octane number (posted at the
pump) must be 91 min. It is an average
of both the Research (R) octane num-
ber and the Motor (M) octane number:
(R+M) / 2). This is also known as the
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not exceed
10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact,
extinguish all smoking materials. Never
allow sparks, flame or smoking materials
near gasoline!
!To maintain the engine’s durability and
performance, premium unleaded gaso-
line must be used. If premium unleaded
is not available and low octane fuel is
used, follow these precautions:

have the fuel tank only partially
filled with unleaded regular and fill
up with premium unleaded as soon
as possible


avoid full throttle driving and abrupt
acceleration


do not exceed an engine speed of
3000 rpm if the vehicle is loaded
with a light load such as two occu-
pants and no luggage


do not exceed
2/3 of maximum ac-
celerator pedal position if the vehi-
cle is fully loaded or operating in
mountainous terrain

449 Technical data
Fuels, coolants, lubricants, etc.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains
10% ethanol and 90% unleaded gasoline,
can be used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Gasoline additives
A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the
use of quality gasoline containing additives
that prevent the build-up of carbon depos-
its.
After an extended period of using fuels
without such additives carbon deposits
can build up, especially on the intake
valves and in the combustion area, leading
to engine performance problems such as:

Warm-up hesitation


Unstable idle


Knocking/pinging


Misfire


Power lossIn areas where carbon deposits may be en-
countered due to lack of availability of gas-
olines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles. Refer to Factory
Approved Service Products pamphlet for a
listing of approved product(s). Follow di-
rections on product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and
may be harmful to the engine operation.
Damage or malfunction resulting from
poor fuel quality or from blending addition-
al fuel additives other than those tested
and approved by us for use on
Mercedes-Benz vehicles listed in the
Factory Approved Service Products pam-
phlet are not covered by the
Mercedes-Benz Limited Warranty.

450 Technical dataFuels, coolants, lubricants, etc.Coolants
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-
vides:

corrosion protection


freeze protection


boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
The coolant solution must be used year
round to provide the necessary corrosion
protection and increase in the boil-over
protection. Refer to Maintenance Booklet
for replacement interval.Coolant system design and coolant used
stipulate the replacement interval. The re-
placement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products pam-
phlet) are used to renew the coolant con-
centration or bring it back up to the proper
level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. - 22°F [-30°C]). If
you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protec-
tion to approx. - 49°F [-45°C]), the engine
temperature will increase due to the lower
heat transfer capability of the solution.
Therefore, do not use more than this
amount of anticorrosion/antifreeze.If the coolant level is low, water and
MB 325.0 Anticorrosion /Antifreeze
should be used to bring it up to the proper
level (have cooling system checked for
signs of leakage). Please make sure the
mixture is in accordance with label instruc-
tions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Center.

451 Technical data
Fuels, coolants, lubricants, etc.
Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum parts. (Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life.)
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0 anticorrosion/anti-
freeze agent.Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to an authorized Mercedes-Benz
Center for service.

Both the windshield and headlamp washer
systems are supplied from the windshield
washer fluid reservoir.
The windshield and headlamp washer fluid
reservoir has a capacity of approx.
7.4 US qt (7 l).
Refill the reservoir with MB Windshield
Washer Concentrate and water (or con-
centrate and commercially available
premixed windshield washer
solvent / antifreeze, depending on am-
bient temperatures).Windshield and headlamp washer fluid
mixing ratio
For temperatures above freezing point, use
MB Windshield Washer Concentrate “S”
and water:


1 part “S” to 100 parts water
(1.34 fl oz [40 ml] “S” to 1 gal [4.0 l]
water)
For temperatures below freezing point, use
MB Windshield Washer Concentrate “S”
and commercially available premixed

Warning!
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze
on hot engine parts because it may ignite
and burn. You could be seriously burned.
